The module includes a measurement device configured to measure at least one electrical parameter of the network, a detector configured to identify a network disturbance and output a switching signal, and a reference generator configured to produce a substitute reference vector for the converter based on the at least one electrical parameter. The module also includes a fault management unit comprising a fault classifier, the unit being configured to interact with the measurement device, detector, and reference generator such that, in the event of an undervoltage during island operation, a quick-action frequency regulator is activated. The regulator acts on the converter to vary a real-power feed P in the event of a discrepancy in a network frequency.

摘要： A method for operating a wind energy installation and a system for implementing the method. An oblique incident flow value, which represents the difference between the wind direction and the direction of a rotor axis of the wind energy installation, and a load value, which represents the load state of the wind energy installation, are determined. A total load value is determined based on the load value and the oblique incident flow value. The rotor rotation speed is reduced when the total load value is above a first limit value. The wind energy installation is shut down when, in addition, a second limit value is exceeded. The method makes it possible to react objectively to oblique incident flows and can reduce a load on a wind energy installation without causing large yield losses.

摘要： A wind energy installation is provided with a generator driven by a rotor with adjustable rotor blades to produce electrical energy, with a pitch adjustment device to adjust the blades, which pitch adjustment device includes an emergency circuit with an energy store to actuate a blade actuating motor. A shunt branch is provided with a current-balancing device in parallel with the energy store, the current balancing device configured to control the current shunt branch depending on a feedback current from the blade actuating motor. A current balancing circuit is provided with which the feedback current occurring in the overrunning state is dissipated in controlled fashion via a shunt branch and therefore the electrical energy store is protected from a damaging feedback current. This prevents a damaging rise in the voltage of the electrical energy store and a rise in the motor speed of the blade actuating motor during overrunning operation.

The installation also includes a plurality of cables which are guided via a loop from the tower into the nacelle, the cables being held at a distance from one another in the loop by means of rotationally fixed and loose holders. The holders each have receptacles for attachment of the cables with a predetermined circumferential separation.

A loop guide is formed such that the loop is subdivided by means of the rotationally fixed lower guide ring into a curved untwisted area and an extended twisted area.

摘要： A wind energy installation includes a wind rotor, a double-fed asynchronous generator driven by the wind rotor, a converter provided with a first part on the generator side connected to a rotor and a second part on the network side connected to a stator of the generator, and a control device providing converter regulation. A mode selector can be switched between a normal operating mode and a reduced voltage operating mode, in which the excitation of the generator is reduced compared to the normal operating mode. The under-excitation produces an additional reactive current, thus reducing the rotor voltage. The rotor voltage can be limited even when the load is high and the network frequency or voltage is incorrect. The usable rotation speed range of the wind energy installation can be extended to provide a more powerful generator with a higher rating, without changing the converter.
